We fell into a routine. Every morning Darcy would wake me up and we’d go for a run. After, we’d shower and dress, then I would make us both smoothies and we’d go to work. I’d go down to the mailroom and sort packages, then deliver them. I met all sorts of very strange, very rich people who apparently stared at computer screens all day. I honestly still have no idea what those people did for a living, but they were all very well compensated for it.
Darcy and I would eat lunch together, then I would walk three blocks west from the building and take the train back home. When I got there, I’d change into more comfortable clothes and make dinner, so it was waiting for my parents when they arrived. Darcy would come back much later and eat the leftovers.
Along with going to work every day, my sister would give me all sorts of jobs. Handjobs in the morning before our run (or after, or a few times during), a blowjob in the men’s room (or the copy room, or at Darcy’s cube) at work, then another at night after she came home. Sometimes I would finger or lick her in return, but it was usually 3:1 in my favor and Darcy seemed fine with that distribution.
By the end of the week I was exhausted. As I passed out on my bed Friday night, I realized I hadn’t smoked up or even switched on my PS4 all week. Eventually, in my half-sleep haze, I felt my sister crawl into bed next to me. We didn’t even bother with sex, just both slept there like the dead.
The next morning, a Saturday thank God, Darcy rolled over looking positively bubbly. Both of us were still in our work clothes from the day before, but Darcy quickly stripped completely naked.
“I don’t want to run in the nude,” I groaned.
“We’ll take a break day,” Darcy said. She started lifting my shirt off me. Through everything we’d done, completely naked sister remained a rare sight. But there she was in all her glory, golden-brown hair hanging down over her chest. Darcy saw me eyeing her and quirked her head at me.
“Sorry,” I said. Some part of me still thought I shouldn’t be perving on my sister.
“I like that you like me,” Darcy said. She climbed down and slurped up my penis. I settled back into enjoying my morning blowjob – one of Darcy’s slow-Saturday-specials – when my sister shifted. She turned around, putting her pussy right over my face. Her scent overwhelmed me.
“We can enjoy each other at the same time,” Darcy said, mouth full of my meat.
Once again, I was surprised at another seemingly obvious variation on our usual procedures. I leaned my head up and started licking at my sister, trying to match her pace. We’d stroked each other off together before, but this felt like a whole new level. I tried my best to concentrate on pleasing Darcy while she pleasured me, but it was hard. Darcy seemed to be having similar difficulties, but I realized that was kind of the fun of it.
Finally, Darcy’s body tightened over mine. Her legs and arms splayed out and she shuddered. Fortunately, having my dick in her mouth kept her from making too much noise. As the orgasm washed over her, Darcy grabbed my cock and pumped me. I responded immediately.
My sister spun around with a goofy grin on her face. We were both covered in each other’s cum. She giggled and kissed me on the lips. It was a quick peck, but we both pulled back like we’d been shocked.
There was a pause where we stared at each other. That was new. Finally, Darcy relaxed and laid down, resting her head on my chest. Idly, she played with my cock, now lying on my thigh and quite soft. In return, I reached over and fondled her breast.
“You like those, huh?” Darcy said.
“They’re kind of incredible,” I said.
“Boys,” Darcy shook her head, “Trust me, the fun part is a bit lower.” She took my hand and put it on her pussy. We both lay there and slowly diddled each other. Nothing came of it. Eventually Darcy got up and left my room. I heard her turn on the shower.
I got up and got dressed, happy to leave my formal clothes in the dresser for at least a day. My parents were already sitting at the table eating breakfast.
“Did Darcy sleep in your room last night?” Mom asked as I went into the kitchen. She offered me coffee, but I started to make a smoothie instead. I couldn’t believe my sister had me hooked on those awful things, but the truth is I felt way better when I drank them instead of the usual crap I put in my body.
“Did she?” I asked, trying to seem confused. Mom gave me her best Mom-stare. “Darcy came in early this morning, I remember,” I said, “She forgot it was a Saturday.”
My Mom continued to eye me as she sipped her coffee.
“I think I’d remember if my sister was in my bed, Mom,” I said.
“Well, your father and I have errands to do,” Mom said, “We’ll be back in about an hour.” She stood up and kissed my forehead. “You need a shower,” she told me, “You smell strange.”
I nodded, hoping she wouldn’t press the issue. A few minutes later, she and Dad drove off. Once they left, Darcy came downstairs. She had on a pair of jeans and a floral, sleeveless blouse.
I handed her a smoothie and she took it, appreciatively.
“Mom says I need a shower,” I said.
Darcy sniffed me. “I like how you smell,” she said, giving me a sultry smile.
My phone gleeped and I looked down. There was a text from a bunch of my friends. They were all getting online to play Call of Duty. I showed my sister, but she shook her head.
“I think we have enough entertainment right here, ourselves,” she said. “Besides, why do you need other people when you have me?”
I didn’t want to argue, so I texted and said I was busy. I got some mean looking emojis back, but I ignored them.
When we were done eating, my sister decided that we should watch a movie. I told her I doubted we’d be welcome back at the theater. Darcy laughed and went into the living room.
She turned on the TV and found something mindless. Then she sat down on the couch and patted the spot next to her. When I sat, Darcy climbed onto my lap. She pressed down, and I realized she was trying to recreate the weekend before.
My sister ran her butt up and down my rapidly growing shaft. She made little noises, but nothing else. I stared at her back while she moved on me. It was kind of painful, kind of pleasurable, and I did my best to focus on the good part.
“Here,” Darcy said. She got off the couch and lay down on her back. Darcy directed me to lie down right on top of her so that my crotch covered hers. “Yes, like that. Now push down. Yes. Yeah. So good.”
Now I felt what Darcy had been enjoying. Pressing into her like this was nice, and I felt myself building towards something even nicer. Darcy felt it too. Her face flushed. We were so exposed, lying on the living room floor on top of each other. If my parents came back early, there would be no denying what we were doing.
That wasn’t enough for Darcy, though. She pushed me off and stripped down to her panties. She had on a pair of canary yellow underwear with a bow at the top. She motioned for me to do the same. Now I was only in my blue boxers.
I lay back down on my sister and, wow, that was much better. Darcy’s bare breasts pressed into my chest. She wrapped her legs around my waist. We moved back and forth on each other quite a bit like lovers. Darcy was breathing hard. She ran her hands through my hair, over my back. It felt really good to grind on my sister.
She paused again. This time she pulled at my boxers. I took the hint and slipped them off. Darcy took off her panties at the same time. I gave her a wary took.
“Just. On top,” Darcy said. Her breaths coming in gasps. I lay back down on my sister. My cock nestled into her warm furrow. We both groaned as we made contact.
We’d done so much. This was something else entirely. We humped against each other on the living room floor. My “uhn uhn uhns” mixing with Darcy’s “ah ah ahs.” The heat of her slippery cunt on my rigid cock.
Darcy squeezed my bare butt tight and I felt my sister cumming under me. She squeaked. Her back arched. Then she shook. On the Darcy Orgasm Scale (or, as scientists refer to it, the DOS), she’d probably hit a 5 or a 6 there. I rated the ones I’d given her orally as a 10, but honestly, I was still calibrating the measurement.
